The Electromechanical Technicians will carry out overhaul of AC and DC motors in a workshop environment, including dismantling, inspection, cleaning, bearing replacement, reassembly, and assistance with rewinding activities. The role includes conducting basic electrical tests such as insulation resistance and continuity, supporting noload/run tests, and completing required overhaul documentation in line with safety standards and workshop procedures. This scope is limited to motor overhaul activities only.
Motor Overhaul & Refurbishment
- Carry out complete overhaul of AC and DC motors in a workshop environment as per approved procedures.
- Perform safe dismantling and assembly of motors, including rotors, stators, bearings, end shields, and cooling components.
- Clean motor components using approved methods (chemical / mechanical) prior to inspection and reassembly.
- Inspect and assess bearings, shafts, rotors, stators, commutators (DC motors), slip rings, and cooling fans for wear or damage.
Electrical Inspection & Testing
- Conduct insulation resistance (IR) testing, continuity checks, and winding resistance measurements before and after overhaul.
- Identify common motor faults such as insulation deterioration, overheating marks, bearing failures, and mechanical imbalance.
- Assist in rewinding activities, including insulation preparation, slot cleaning, varnishing support, and postrewind checks.
- Record test results and report abnormalities to senior technicians or supervisors.
Mechanical Work During Overhaul
- Perform bearing removal and installation, including heating and fitting methods under supervision.
- Carry out shaft alignment checks, runout measurement, and balancing support (as applicable).
- Ensure correct reassembly with proper clearances, torque tightening, and alignment of components.
Reassembly, Testing & Handover
- Support reassembly of motors according to drawings, manuals, and standard overhaul practices.
- Assist in noload and trial run tests to verify rotation, vibration, noise, and temperature.
- Ensure motors are fit for final inspection and site dispatch after overhaul completion.
Safety & Workshop Compliance
- Follow electrical and mechanical safety practices, LOTO requirements (where applicable), and workshop SOPs.
- Use appropriate PPE, tools, lifting equipment, and handling methods during overhaul activities.
- Maintain good housekeeping standards within the overhaul workshop.
Documentation & Reporting
- Complete overhaul checklists, job cards, and test reports accurately.
- Update motor history records and highlight repeat failures or improvement recommendations.
- Assist in preparation of documentation for QC checks and audits.
Education & Experience
- ITI (Electrician) or equivalent technical qualification is required.
- Minimum 3 to 5 years of handson experience in AC and DC motor overhaul within a workshop or industrial environment.
- Proven experience in motor dismantling, inspection, cleaning, and reassembly.
- Handson knowledge of bearing removal and replacement and mechanical checks.
- Ability to perform basic electrical tests, including insulation resistance (IR) and continuity testing.
- Experience supporting motor rewinding activities and noload / trial runs under supervision.
- Familiarity with workshop safety practices, SOPs, and documentation requirements.
